我编写了一个简单的代码来获取一个绿色块,这是我的精灵在屏幕上滚动。当游戏开始时,精灵会出现在屏幕的中央,但是当我运行我的代码时,屏幕只是黑色而绿色块不会出现,除非我点击窗口上的x十字以退出屏幕,然后它会在窗口关闭时显示一秒钟。任何想法我如何解决这个问题。
import pygame, random
WIDTH = 800 #Size of window
HEIGHT = 600 #size of window
FPS = 30
WHITE = (255, 255, 255)
BLACK = (0, 0, 0)
RED = (255, 0, 0)
GREEN = (0, 255, 0)
BLUE = (0, 0, 255)
class Player(pygame.sprite.Sprite):
#sprite for the player
def __init__(self):
pygame.sprite.Sprite.__init__(self)
self.image = pygame.Surface((50, 50))
self.image.fill(GREEN)
self.rect = self.image.get_rect()
self.rect.center = (WIDTH/2, HEIGHT/2)
def update(self):
self.rect.x += 5
#initialize pygame and create window
pygame.init()
pygame.mixer.init()
screen = pygame.display.set_mode((WIDTH, HEIGHT))
pygame.display.set_caption("My Game")
clock = pygame.time.Clock()
all_sprites = pygame.sprite.Group()
player = Player()
all_sprites.add(player)
#Game loop
running = True
while running:
clock.tick(FPS)
for event in pygame.event.get():
#check for closing window
if event.type == pygame.QUIT:
running = False
#update
all_sprites.update()
#Render/Draw
screen.fill(BLACK)
all_sprites.draw(screen)
pygame.display.flip()
pygame.quit()
答案 0 :(得分:0)
更新精灵,填充屏幕和绘制精灵的所有代码都在主循环之外(while running
)
你必须记住身份Python的语法:你的命令就在你的主循环之外。
此外,我强烈建议将mainloop置于适当的功能中,而不是将其留在模块根目录上。
